Fix signal/slot problem with quicksubscription example

Browse Source 
The example does not build with latest changes.

As it turns out there is a mismatch between the topic property
and the connected signal. Since the signal is not used, it is
removed in the hope that it will then build.

The error message from the build is:

Failure Summary:
The build failed due to a compilation error in 'qmlmqttclient.cpp'.
The function 'QmlMqttSubscription::topicChanged()' was called without
the required 'QString' argument.

Log snippet:
error: no matching function for call to ‘QmlMqttSubscription::topicChanged()’
note: candidate: ‘void QmlMqttSubscription::topicChanged(QString)’
note: candidate expects 1 argument, 0 provided
